Signal Mountain Happenings

Christmas Underground returns this holiday season to Ruby Falls! From December 1-18 on Thursdays through Sundays, then daily from December 19-23, take a magical adventure deep within the heart of Lookout Mountain where children discover a secret underground passage to see Santa!

Visit the decorated gemstone mines in this unique setting 26 stories underground. Adventurers go on a journey past the Northern Lights and Sugar Plum Fairy Village, into a tunnel (optional), through an ice cave and to the North Pole where Santa awaits!

This festive event is made for children. Kids will meet Ruby Falls gemstone miners and enjoy interactive fun like panning for gems called "joystone" (which spreads the spirit of Christmas), using the joystone tester and cracking their own joystone geode.

Ruby Falls remains 60 degrees year-round making it the perfect atmosphere to experience nighttime magic during the day. Christmas Underground is in a separate part of the cave from where regular Ruby Falls tours are held. Combo tickets are available for the holiday event and the cave and waterfall tour.

Ruby Falls is America’s deepest commercial cave and largest underground waterfall open for public viewing. It features a 145-foot waterfall located 1,120 feet beneath the surface of Lookout Mountain in Chattanooga, Tennessee. LED lighting is used throughout the castle and waterfall.
